Updated April 20, 2023
Notice to ArcGIS Pro Users: ArcGIS Knowledge desktop users should not download ArcGIS Pro 3.1 until their GIS Administrators upgrade the existing ArcGIS Knowledge servers to ArcGIS Server v11.1, which were released April 20, 2023. Please coordinate your upgrade needs with your ArcGIS Enterprise Administrator.
Notice to ArcGIS Administrators: Please coordinate with ArcGIS Knowledge users and developers before upgrading to ArcGIS Enterprise 11.1 to prevent any disruption in work.
What is happening?
In order for ArcGIS Knowledge applications to support existing data in supported User Managed NoSQL Data Stores, e.g. Neo4j graph databases, the ArcGIS Knowledge services specification in ArcGIS Enterprise 11.1 will change such that earlier ArcGIS Pro versions prior Pro 3.1 will not be able to connect with the new ArcGIS Knowledge Graph services. Similarly, Knowledge functionality in ArcGIS Pro 3.1 will not be able to save new work with older versions of ArcGIS Knowledge services (in Enterprise 10.9.1 or 11.0).
How will it impact different Knowledge users?
For ArcGIS Knowledge Pro users, nothing needs to be done immediately. However, ArcGIS Knowledge users should NOT download ArcGIS Pro 3.1 at their primary workstation when it becomes available. It will not be compatible with existing ArcGIS Knowledge services. When the organization GIS Administrator upgrades their ArcGIS Knowledge Server to ArcGIS Enterprise 11.1, users can then download ArcGIS Pro 3.1 or a later version, and save their existing ArcGIS Pro projects that include Knowledge investigations within the new Pro 3.1 user interface. If your organization remains on ArcGIS Enterprise 10.9.1 or 11.0, users will NOT be able to upgrade to Pro 3.1 and continue to save work on existing ArcGIS Knowledge investigations.
ArcGIS Enterprise administrators using ArcGIS Knowledge in Enterprise 10.9.1 or 11.0 will follow the normal Enterprise Server Upgrade pattern. Administrators should work with users of ArcGIS Knowledge to plan the timing of their Pro and Enterprise upgrades to ensure no disruption of work.
Why the change?
ArcGIS Knowledge enables analysts in organizations to connect, analyze and visualize large amounts of disparate data together as enterprise knowledge graphs. Some organizations have already invested in modeling, organizing and storing connected data in existing graph databases (e.g. Neo4j) or multi-model databases with graph support (e.g. Amazon Neptune, Microsoft Azure CosmosDB).
With ArcGIS Enterprise 11.1, ArcGIS Knowledge will support Neo4j Enterprise Edition as Esri’s first supported NoSQL Data Store with user managed data. This breaking change enables critical changes that allows organizations to leverage data stores with user managed data without needing to manage that data using ArcGIS exclusively.
ArcGIS is an open and interoperable system, allowing customers to own their data pipelines. ArcGIS intends to connect directly to more third party, user-managed graph and multi-model data stores in order to help enterprises combine the power of spatial and graph analytics while leveraging their existing IT architecture investments. In order to enable ArcGIS applications and developer tools to leverage these user-managed graph data more seamlessly, the product team needed to implement a new, more flexible engineering pattern within the Knowledge graph service. This technology change, unfortunately, is not backwards compatible with previous versions of the service.
